1 Claim.

The invention relates to new and useful improvements in a foldable fibercontainer which is especially adapted for crating eggs, fruits and thelike for commercial handling.

An object of the invention is to provide a fiber container which may bemade from a single rectangular blank by slitting and scoring wherein thecontainer when assembled includes two substantially identical cells ofequal capacity, the Walls of which are rigidly connected and housedsolely within a bottom wall, side walls and a cover when the containeris closed.

A further object of the invention is to provide a container of the abovetype wherein the back wall of the container is stitched to the rearwalls of the cells and the front wall of the container is stitched tothe front wall of the cells, thus providing a rigid container structurebefore loading and closing.

A still further object of the invention is to provide a container of theabove type wherein the inner end walls of the cells are provided withflaps which are folded back onto the outer side wall of the cell andstapled thereto.

A still further object of the invention when found desirable is toprovide a liner which reenforces the bottom wall of the container andalso the end wall of the container.

A still further object of the invention is to provide when founddesirable a liner for the container which has extensions adapted toserve as a cover for the container, thus making a double wall cover aswell as double wall ends and double wall bottom.

These and other improvements will in part be obvious and will in part behereinafter more fully disclosed.

In the drawing:

Figure 1 is a plan view of a body blank which has been slit and scoredso that a container may be formed therefrom embodying the invention;

Figure 2 is a. perspective view showing the blank as folded so as toprovide cells, the front wall of the blank being unfolded so as to showthe flaps for securing the cells in assembled position;

Figure 3 is a view similar to Figure 2, but showing the rear wall asstitched to the cells and also the front wall as folded so as to providea front wall for the container which is stitched to the flaps and thefront side walls of the cells;

Figure 4 is a view showing the container closed and sealed by a sealingstrip;

Figure 5 is a perspective view on a smaller scale showing a slightlymodified form of con- 2 struction wherein the fiaps extend to the fullheight of the front side walls of the cells;

Figure 6 is a longitudinal sectional view through the container showinga modified form wherein the container is provided with the linerextending lengthwise of the bottom and to the full height of the endwalls;

Figure '7 is a longitudinal sectional. view showing a furthermodification wherein the liner at each end thereof has an extensionwhich serves as an inner cover when moved to closed position; and

Figure 8 is a longitudinal sectional view through the container showinga further modification wherein the liner at one end thereof only isprovided with an extension forming an inner cover extending the wholelength of the container.

The invention has to do with a fiber container which is made from asingle blank, preferably of corrugated board. The blank is substantiallyrectangular in outline and is slit along parallel lines. so as toprovide side walls which are in tegral with the bottom of the containerand a cover section which is integral with the rear side wall. Theseslits also provide end walls which are integral with the bottom, sidesections projecting laterally from the end sections and forming the sidewalls of cells and an inner end section for the cells which are providedwith flaps adapted to rigidly connect the walls of the cells.

Referring more in detail to the drawings, the blank from which thecontainer is formed is shown in Figure 1. It is substantiallyrectangular in shape. The blank is slit along the lines I, I, so as toprovide a bottom 2, a rear side wall 3 and a cover 4. The rear side wallis separated from the bottom by a score line 5- and the cover isseparated from the rear side wall by a score line 6. The cover 4 isprovided with a flap 1 which is separated from the cover by a score line8. The blank is also slit along the lines 9, 9 to provide a front wallI0 which is separated from the bottom by a score line I I. These scorelines, of course, are not cut through the blank but are of sufiicientdepth to aid in forming a fold line. The blank is of sufiicient width soas to provide an end section I2 separated from the bottom by a scoreline I3.

At the other end of the bottom is an end section I4 separated from thebottom by a score line I5. These end sections when folded to an uprightposition relative to the bottom form the end walls of cells in which theproduct is to be placed. The end section I2 is provided with a sectionIt which is separatedfrom the end I2 of this cell. The flap 28,

by a score line H. At the other side of the end section there is anextension |B separated from the end wall |2 by a score line l9. Thesesections l6 and I8 when in folded position form the side walls of one ofthe cells. There are similar sections 20 and 2| at the sides of the endsection M which are separated from the end sections by score lines 22and 23 respectively. These extensions 20 and 2| form the side walls ofthe other cell in which the product is placed.

The section l6 has a further extension 24 separated from the section l6by a score line 25. There is a similar extension 26 carried by thesection 20 and separated therefrom by a score line 21. These extensions24 and 26 form the inner end walls of the cells. These end walls areeach provided with a flap, one of which is indicated at 28 and the otherat 29. These flaps are separated from the extensions carrying the sameby score lines 30, 30. This blank lends itself to slitting and scoringoperations as differentiated from die cutting. This blank may be shippedin flat condition and then assembled for use as a container.

In Figure 2 of the drawings the end section l2 and I l are foldedupwardly from the bottom. The sections l8 and I8 are folded so as toform the side walls of one of the cells. The extension 24 is folded soas to form an inner end wall if used, is folded onto the outer face ofthe front side section of the cell and may be stapled thereto so as tohold the cell rigidly in assembled position. The end wall I4 is likewisefolded to vertical position to form the end wall of the other cell. Theextensions and 2| are folded in position so as to form the side walls ofthis other cell. The extension 26 is folded in position so as to formthe inner end wall opposed to the end wall M. The flap 29 is folded ontothe outer face of the front side wall of the cell and may likewise bestapled to the front wall for forming a rigidly assembled cell. Thesetwo cells just described are identical in shape and height and aretherefore of equal capacity. The section 3 is folded along the scoreline 5 to the position shown in Figure 2 and this provides the rear wallof the container. As viewed in Figure 2, the front wall ID has not yetbeen folded to vertical position.

In Figure 3, this front wall In is shown as r folded to a verticalposition, and when so positioned it contacts in part with the flaps 28and 29 and in part with the front side walls l8 and 2| of the cells. Asshown in this Figure 3, the rear wall is stitched, preferably by staplesindicated at 3|, to the rear side walls of the cells. Likewise the frontwall In is stitched preferably by staples 32, 32 to the flaps and to thefront side walls of the cells. This makes a very rigid containerconstruction ready for loading.

It is noted that the flaps 28 and 29 do not extend to the full height ofthe side walls as shown in Figure 2. These flaps space the front wall IDfrom the side walls l8 and 20, thus providing a pocket. This will permitthe flap 1 of the cover, when in closed position, to be inserted in thepocket between the front wall In and the front side walls l8 and 2| ofthe cells. After the cover has been moved to closed position and theflap placed between these sections, then a sealing strip 33 may beapplied which extends from one end of the container to the other andfirmly secures the cover in closed position.

In the modification illustrated in Figure 5,

the flaps on the end walls of the cells extend to the full height of theside walls and the flap 1 of the cover is cut away in the centralportion thereof so as to form two flaps l 1 which may be insertedbetween the front wall H! of the container and the outer portions of thefront side walls l8 and 2| of the cells.

The container above described is made from a single foldable fiber blankwhich may be readily folded and assembled to provide independent cellsof equal capacity housed within a bottom wall, side wall and a coverwherein the front and rear walls when in assembled position may bestitched to the cells for providing a rigid construction. For certainuses it may be desirable to strengthen the bottom and end walls.

In Figure 6 there is shown a liner 33 which extends the full length ofthe bottom wall 2 and likewise the full width of the bottom wall. Thiswill reenforce the bottom wall. The partitions 24 and 26 are shortenedslightly to permit the liner to extend beneath the same. The liner hasan extension 34 which serves as a reenforcement for the end wall l4 andalso an extension 35 which serves as a reenforcement for the end wallI2. The liner at the ends extends all the way to the upper end of theend walls of the cells.

In the modification shown in Figure '7, the liner 33 is provided withfurther extensions. The extension of the end liner wall I34 provides aninner cover section 36 and the extension of the end wall 35 provides aninner cover section 31. These inner covers 36 and 31 are each providedwith flaps 38, 38 and the flaps when the covers are in closed positionextend between the partitions 24 and 26. This makes a. container whichhas a double bottom wall, double end walls, double front and rear wallsand a double cover.

In Figure 8, the end liner wall 35 has an ex-- tension which forms aninner cover 39. This inner cover extends from one end of the box to theother and is provided with a flap 40 which extends down between the endwall l4 and the liner end wall 34. This also produces a containerwherein there is a double cover as well as double walls throughout.

While the flaps 28, 29 have been illustrated and are preferred, it willbe understood that they may be omitted and tape employed for securingthe end walls of the cells to the front side walls of the cells.

It is further understood that minor changes in the details ofconstruction may be made without departing from the spirit of theinvention as set forth in the attached claim.
